Chofu Aerospace Center, Japan Aerospace Exploration Agency (JAXA)(CAC)), Chofu, Tokyo, Japan, Since the beginning of space engineering development, many objects have been emitted to space, and the number of debris has increased rapidly. It is now estimated that about 20,000 debris of various shapes and sizes exist in space. As the space environment deteriorates, various efforts to grasp and avoid the possible threat of space debris, such as colliding into spacecraft and re-entering to the Earth, have been conducted worldwide. The efforts consist of observing the space debris, calculating their orbits, and cataloging them, and these are called ''Space Situational Awareness'' or SSA activities. At JAXA, our SSA activities include observations of space debris using radar at Kamisaibara Space Guard Center and optical telescopes at Bisei Space Guard Center, orbit determination, risk evaluation of space debris approaching our satellites, and avoidance maneuver operations. In this presentation, we introduce our SSA activities at Space Tracking and Communications Center and the outline of our new SSA system., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1830034004, レポート番号: JAXA-SP-18-011}, title = {Activities on Space Situational Awareness at STCC, JAXA}, year = {2019} }
